| Identification and Conservation of a New Species of Pithecia in Amazonian Ecuador Marsh, L.K. Understanding primate diversity is vital if we are to conserve it. Despite recent taxonomic research and reviews by Philip Hershkovitz, diversity in the Amazonian genus Pithecia is still poorly understood. Here we describe our observations of a saki monkey of this genus in the Yasuni Biosphere Reserve at the Tiputini Biological Station (TBS), Ecuador. According to the range hypothesized by Hershkovitz it should be attributable to Pithecia aequatorialis. It is not. It is probable that it is a new species or subspecies, and we describe our ongoing studies to ascertain its identity through field observation, genetic analysis and comparison with museum specimens. volta a programação do simpósio |
